JSON Viewer

JSON Viewer

View and explore JSON data as an interactive tree. Expand or collapse objects and arrays, copy paths and values, search in the tree, and load from a URL. Your input is saved in your browser. All processing runs in your browser; no data is sent to any server.

Key features

• Tree view: Navigate nested objects and arrays with expand and collapse.
• Search: Filter the tree by key or value; matches are highlighted and expanded.
• Copy path or value: Copy the path or the value at any node for use in code.
• Type highlighting: Keys, strings, numbers, booleans, and null values are styled for quick scanning.
• Query tab: Run JSONPath expressions; list matches and copy tree paths or values.
• Formatted tab: Switch to pretty-printed JSON when you need the raw text.
• Load from URL: Fetch JSON from a public, CORS-enabled URL (with size and timeout limits).
• Saved in your browser: Your last input and expanded state are restored on return.
